Inclined plane problems and answers
WebPhysics questions and answers; Why is a rotated coordinate system used to solve an inclined plane problem?* 2 points O To minimize the number of forces that need to be considered. OTo eliminate the need to consider the force of gravity. To align the coordinate axes with the acceleration of the object on the plane. WebWhat do solved examples involving inclines look like? Example 1: Snowy sliding sled A child slides down a snowy hill on a sled. The angle the hill makes with respect with horizontal is \theta=30^o θ = 30o and the coefficient of kinetic friction between the sled and the hill is \mu_k=0.150 μk = 0.150.

WebBut it's an interesting type of problem. Because what we're going to do is, we're going to launch a projectile on an incline. So maybe we're on the side of the hill. So it's a hill. Let me do it in green. So let's say we're on the side of the hill like this. And let's say that we know the inclination of the hill. WebHowever, this is not the process that we will pursue with inclined planes. Instead, the process of analyzing the forces acting upon objects on inclined planes will involve resolving the weight vector (F grav) into two perpendicular components. This is the second peculiarity of inclined plane problems. The
